Q: Why can't I match on the BCC: header? 

A: You can't match on the BCC: header because it is not present in the
message you receive. See above. This is what the "Blind" in "Blind
Carbon Copy" stands for; none of the recipients are supposed to see
who's been BCC:ed. (Okay, so the spec has a few more twists. This is how
Sendmail does it. Some other mailers will show the BCC list to the
people who are being BCC:ed.) 

Q: The Received: header seems to often contain something like Received:
from elsewhere (...) by somewhere (...) for <[EMAIL PROTECTED]> even
if the recipient was Bcc:ed -- can't I rely on that "for" part? 

A: No. Next question? 

The problem is that (a) not all MTA:s add this information, and (b) even
if yours sometimes does, it might not always. E.g. Sendmail won't stamp
the recipient in the Received: header if the message was sent to several
recipients at your site. 


I know this doesn't help but at least you now know why.

Cheers
Nigel
